Why were most of the reforms applied to the middle and upper class (time of enlightenment)?

During the Enlightenment period, reforms were primarily applied to the middle and upper class because these groups had more wealth, education, and influence to push for change. The middle and upper class were also seen as more capable of handling the responsibilities that came with reform, such as participating in governance and upholding new ideas like individual rights and freedom. Additionally, these classes were often the target audience for Enlightenment philosophers who sought to spread their ideas and spark societal change.
